FIG. 1 is a diagram of the internal structure of the electronic photo frame in the first embodiment of the present invention.

Detailed ways

Please refer to FIG. 1 , which is an internal structure diagram of the electronic photo frame in the first embodiment of the present invention. The electronic photo frame 1 includes a processing unit 10 , a power supply 20 , a brightness sensing unit 30 , a motion sensing unit 40 , a power management unit 50 , a display panel 60 and a memory 70 . The memory 70 stores various multimedia files, such as audio files, video files, and digital pictures. The electronic photo frame 1 is mainly used for displaying and playing the multimedia files.

Wherein, the power supply 20 is connected with the power management unit 50 . The power source 20 can be a battery or an AC/DC adapter module. The power management unit 50 is respectively connected to the processing unit 10 , the brightness sensing unit 30 , the motion sensing unit 40 and the display panel 60 and distributes operating voltages to them. In this embodiment, when the electronic photo frame 1 is connected to the power supply 20, the power management unit 50 distributes operating voltages to the processing unit 10 and the motion sensing unit 40, and the processing unit 10 and the motion sensing unit 40 are in the working state. Instead, other components may not be powered to make them in a non-working state.

The motion sensing unit 40 is also connected to the processing unit 10 for detecting whether there is human activity within a certain range. And if the motion sensing unit 40 detects the activities of people within a certain range around, the motion sensing unit 40 generates a human body induction trigger signal and sends it to the processing unit 10 .

Wherein, after receiving the human body induction trigger signal, the processing unit 10 controls the power management unit 50 to distribute voltage to the brightness sensing unit 30 , thereby turning on the brightness sensing unit 30 . The brightness sensing unit 30 is also connected to the processing unit 10 , and further detects the current ambient brightness value after being turned on, and generates a brightness trigger signal and sends it to the processing unit 10 when the current ambient brightness value is lower than a predetermined value. The processing unit 10 judges whether the brightness trigger signal transmitted by the brightness sensing unit 30 is received, and if the brightness trigger signal is received, the processing unit 10 sends an opening control signal to the power management unit 50, so that the power management unit 50 is The display panel 60 distributes the operating voltage, and the display panel 60 of the electronic photo frame 1 is turned on to be used as illumination. In other implementations, the processing unit 10 can obtain clock information from a clock unit, and control to display the clock on the display panel 60, so as to provide the current time to people around.

The motion sensing unit 40 detects whether there is human activity within a certain range every predetermined time interval, and if no human activity is detected within a certain range, it sends a closing signal to the processing unit 10, so that the processing unit 10 generates a When the control signal is turned off and sent to the power management unit 50, the power management unit 50 stops distributing voltage to the display panel 60 and other components.

Therefore, when it is detected that there are people around and the ambient brightness is lower than a predetermined value, the display panel 60 of the electronic photo frame 1 is turned on for lighting, and when there is no one around, the electronic photo frame 1 automatically turns off the display panel 60, reducing the power loss.

The motion sensing unit 40 can be one of an infrared sensing unit, an ultrasonic sensing unit and a voice sensing unit. Among them, the infrared sensing unit detects whether there is human activity within a certain range through the infrared rays radiated by the human body. The voice sensing unit judges whether there is someone within a certain range by sensing human voice. The movement of the human body is used to determine whether there is a person within a certain range.

The electronic photo frame 1 also includes an input unit 80 and an interface unit 90 . The input unit 80 is used for the user to operate the electronic photo frame 1 , and the interface unit 90 can be a wired interface (such as a USB interface, etc.) or a wireless interface (such as a wireless communication module).
